STERILIZER.

SPECIFICATION forming part of Letters Patent No. 683,807, dated October 1, 1901. Application filed May 31, 1901 Serial No. 62,530. (No model.)

To @ZZ whom, it may concern:

Be it known that we, JOSEPH ScHonTrL and CHRISTIAN JAEGER, citizens of the United States, and residents of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Sterilizer, of which the following is a full, clear, and exact description.

This invention relates to an apparatus for sterilizing by the use of su perheated steam; and it consists in certain novel features of construction and arrangement of parts, as will be hereinafter fully described and claimed.

This specification is a speciiic description of one form of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters oi' reference indicate corresponding parts in the several views.

Figure l is a side elevation of the invention with parts broken away. Fig. 2 is a similar elevation taken from a different point of view, and Fig. 3 is a detail view of the three-way cock.

The apparatus comprises a boiler d and a chamber b, in which the sterilizing is performed. A wateigage may be fitted to the boiler d, and a feed and safety valve device d may also be employed. In Fig. l, e indicates a suitable means under the boiler for heating it, which means may be of any sort desired. Passing out of the upper part of the boiler ct is a pipe f, extended down under the boiler and coiled, as indicated in Fig. 1. It then passes up the opposite side of the boiler, where it is fitted with a three-way cock g, one port of the cock communicating with the boiler at its lower portion. The upper extremity of the pipe f is extended into the sterilizing-chamber b and perforated to form a rose or sprayer f2, as shown in Fig. l.

In the use of the invention the boiler is filled with water and heat is applied thereto. The cock g is manipulated so that communication between the coil f and the extension f2 will be closed and communication between the lower part of the boiler a and the coil f will be opened. As heat is applied to the boiler the water will circulate through the cock g into and through the coil f', and the steam and boiling water will pass through the pipe f back into the boiler. This circulation may be continued as long as desired, and when the proper degree of heat has been reached the cock g should be manipulated so as to close the communication between the pipe f and the lower part of the boiler and open the communication between said pipe or coilf and the end f2 of the pipe. The

. steam from the boiler ct will then pass through the pipe f and coil f and thence through the rose or extension f2 into the sterilizing-chamber b, where it may be made to perform the desired work. As the steam passes through the parts f and f it will be superheated and will enter the sterilizing-chamber in proper' condition for the most effective work.

The three-way cock g may be of any desired construction, its detailed form being wholly immaterial. It is only essential that there be provided some means for controlling the pipe f and also for controlling the communication between said pipe and the lower part of the boiler.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The combination of a boiler, a pipe passing downward from the upper portion of the same and thence leading away from the boiler, and a three-way cock controlling the pipe and also controlling a communication between said pipe and the lower portion of the boiler, for the purpose specified.

2. A sterilizer, comprising a boiler, walls forming a sterilizingchamber arranged above the boiler, a pipe passing downward from the' upper portion of the boiler and thence lead# ing into the sterilizing-chamber, and a threeway cock controlling said pipe and also controlling a communication between the lower part of the boiler and the pipe, for the pure pose specified.

The combination of a boiler, a pipe passnames to this specification in the presence of ing downward from the upper part thereof two subscribing Witnesses. and extending beneath the boiler and thence beyond it, and a `three-Wawy cock controlling y 5 said pipe and also controlling a oommunication bet-Ween the lower part of Iche boiler Witnesses: and the pipe.

In testimony whereof we have signed our JNO. M. RITTER.
